Application filed October 6, 1926. Serial No. 139,923.

.This invention relates to fireworks and more particularly to that classof fireworks4 known as a toy torpedo which comprises a container for an explosive compound and 5 some means for initiatingl the explosion of the compound when the torpedo receives a violent impact, such as upon strikinga hard 20. with aA surface so` as toabrade the explosivey material between the two when aV violentimpact is given to the torpedo."

`A still further objectof the invention consists in the provision of a torpedo having a completely enveloping container, partially filled" with a loose explosive compound and having, projecting inwardly into the explo- 'sive chamber, a bendable member, said member anda wall of the container having abrasive surfaces adapted to be brought together to ignite the explosive compound upon impact of the torpedo. 'I

` The above and other objects'of the invention will be more apparent, to'tho'se skilled in the art, after a consideration ofthe following` specification and accompanying drawings, wherein are disclosed, by way of example only, a single embodiment of the v1nvvention` with the understanding, however, 40 that various changes may be made therein witlioutdeparting from the spirit of the in- 5 `vention or the scope of the appended claims. In said drawings: 'v v l Figure 1 is a perspective view of one form of torpedoA constructed according to the present invention; y

' kFigure 2 is a c entral longitudinal section through'such a torpedo; and i yFigure is a transverse section on line 3-3 of Fig. 2. I 'A Toy torpedoes, as usually made, comprise a more-or less rigid vcontainer completely enclosingi a" compartment in which is arranged av powdered explosive composition. e5 Small granules or particles of gravel-or simiu 1er abrasive materiel of enicent sise to considerable weightand momentum4 are mixed with the explosive, so 'that when the torpedoreceives a violent impactthe particles of gravel abrade against each other andy ignite the explosive. `This type of torpedo is'unsafe to manufacture and to handle durf ing shipping and storing, for the loose particles of gravel may so rub against eachother, due to slight jars incident to handling, as to cause the explosive to ignite. The ignition of a single torpedo in acase will lcause the4 explosion of the whole case and may result in large property damage and even loss of life. The present torpedo, while following the style of thev torpedo just described, *in

- sures safety, except upon intentional .impact to explode the torpedo, by securing all ofthe abrasive material to portions of the container which are relatively stationary` and spacedA apart, except at the'timeof the intentional and violent impact,whenthey move toward the explosive material;

Referring to the drawings, it will be seen that for the'sake of convenience and simplicity a tube' type.` of torpedo.y has been diseach other and cause the abrasive 4to ignite closed. The main .body of thekr container is formed from a cylindrical 'tube 10'y made v-of paper, cardboardor any material whichv is not brittle and which will only. bend and not break upon impact. The tube is adapted to be closed-'at its ends by the caps lland 12,

which are formed to telescope over'the tube' and be secured thereto' in anysuitable manner, such as by anadhesive. Obviously the' capsmay fit within the tube or may even be only disksvsecured inthe ends of the tube, their sole'function being to retain the explo.- sive material in the tube and to offer a material-resistance to the expanding gasesk resulting` from the explosion so as to cause aA loud report.- To further increase the resistance of the complete container to the expande ingvgaseslit may be covered with a-gastight and preferably waterproof covering 13."

This Amay take the form of suitably impregit may be a glue 0r other plastic or mastic II'naterialwhich `is applied to the container in a heated orV diluted condition, after thetorpedohas been completed, and allowed toV dry natedfpaper wrapped around the torpedo, or l iiewever, provided@ with 'an 'returned t11buabrasive surfaces, al cap on the other end of' said tube and a gastight covering over said tube and caps. i

8. In a toy torpedo, in combination, a tube open at the ends, closures for said ends forming a compartment Within the tube, explosive material in said compartment, and a member projecting into said compartment, said member being arranged substantially centrally of the tube.

' 9. In a toy torpedo, in combination, a tube open at the ends, closures for said ends forming a compartment Within the tube, explosive material in said compartment, and a pliable member projecting into said compartment, 15

said member v being arranged substantially centrally of the tube. K

10. In a toy'torpedo, in combination, a tube open at the ends, closures for said ends forming a compartment Within the tube, eX-A plosive material in said compartment, and

a pliable member projecting into said com-y partment, said member being arranged substantally centrally of the tube and having an abrasive surface.

In testimony whereof I hereunto aix my signature.
